'6 Claims.

The present invention relates .to a novel carpet sweeper including a disposable dust receptacle, and to cooperating means embodied in the carpet sweeper and dust receptacle for removably retaining said dust receptacle in position within the carpet sweeper and for maintaining said dust receptacle in open condition to receive material swept up by the rotating brush of the carpet sweeper. Y

More specifically, the invention relates to a carpet sweeper including a housing of simplified construction, said housing having a plurality of permanent magnets mounted therein; and to a disposable dust receptacle insertable through the open bottom of the housing. one on either side of the brush, each receptacle having a cover flap provided with at least one ferrous metal disc adapted to engage with a permanent magnet on the housing to retain the cover flap in open condition when in use.

The invention further relates to a disposable dust receptacle which is constructed so that it can be folded into a substantially at condition for convenience in packaging and shipping.

The principal object of the invention is to providea simplied carpet sweeper construction in which the sweeper housing is not required to have a hinged or removable top to afford access to the dust-collecting means Within the housing.

Another object of the invention is to provide a' carpet sweeper having a dust-collecting receptacle that can be readily removed and discarded when substantially full, and readily replaced by a fresh, unused receptacle.

Another object of the invention is tol provide a dust receptacle for use infcarpet sweepers that can be made of cheap paper or any other suitable material and discarded after use.

Still another object of the invention is to provide a dust receptacle adapted for use in carpet sweepers or the like constructed so thatit can be folded into a fiat condition. and thus occupy a minimum of space in packaging, shipping, etc.,but which, nevertheless, can be readily distended for use. I

A still further object of the invention is to provide a carpet sweeper including permanent magnets arranged so that they serve the dual purpose of (l) aiding in retaining a disposable dust receptacle in position within the housing and (2) maintaining the top flap of the dust-collecting receptacle in open position.

Other objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawings, in which:

Fig. 1 is a plan view of a carpet sweeper including dust-collecting receptacles embodying the principles of the present invention;

Fig. 2 is an inverted plan view .of the carpet sweeper, with one of the dust receptacles removed; f

Fig 3 is a vertical, transverse sectional view taken on the line 3-3 of Fig. 1;

Fig. 4 is a longitudinal sectional view taken o the line 4--4 of Fig. 3;

Fig. 5 is an enlarged sectional view takenon' the line 5-5 of Fig. 3, and particularly illustrating the manner in which the permanent magnets are secured to the housing; n

Fig. 6 is a perspective View of one of the dust receptacles; y a Fig. 7 is an end view of the dust receptacles showing the same when in its collapsed or folded condition; and

Fig. 8 is a sectional view through the dust receptacle, taken on the line 8-8 of Fig. 7.

Referring now to the drawings, the housing of the carpet sweeper is generally identiiied by the numeral ID and is preferably made inthe form of a one-piece sheet metal stamping, including an integral arcuate top wall portion yII and' longitudinally extending side walls I2 which merge into said top wall portion. The housing ID also includes end walls I3, which extend downwardly from the top wall portion I I and also con neet with the longitudinal side walls I2. The side walls I2 and the end walls I3 extend outwardly at their lower edges to form flanges I4 and I5, respectively, which serve as a support for a continuous protective rubber ring I6 adapted to prevent the marring of furniture when the carpet sweeper is in use. Thus, the housing I0 is open for its full area at the bottom end thereof, and its top is devoid of a hinged door or removable panel as in conventional carpet sweeper constructions. a n

The top wail portion II (Figs. 1 and 2) is provided with a transversely extending slot I'I adjacent each of the end walls I3. The ends of a bail I8 extend through the slots I'I and are pivotally connected with a shaft I9, which rotatably supports a conventional sweeper brush 20. The sweeper brush 20 includes cylindrical end portions ZI (Fig. 2), which are engaged by brushdriving wheels 22 rotatably supported on studs 23 mounted upon the end walls I3 in any suitable or conventional manner. The bail I8 has a socket 24 mounted thereon, as best shown in Fig. l, and a handle 25 is threaded into said socket, and provides means whereby the sweeper can be moved back and forth across a iioor while supported upon the wheels 22 to eiect rotation of the brush 20, in a manner well understood in the art.

A pair of longitudinally spaced brackets or supports 26 is adapted to be mounted interiorly of the housing Hl upon each of the side walls |2. Thus, each of the brackets, 26 includes an upwardly extending flange 2in which is welded or otherwise secured to the side walls I2, and anzinwardly extending iiange 2? disposed in substantially the same plane as the iianges |4. The

flanges 2l' of each pair of brackets 26 are adapted' to support and to be engaged by the bottom wall 28 of a disposable dust receptacle 29.

The dust receptacle 29 may be made of any suitable material, but is preferably made of inexpensive paper, thereby making it economically feasible to discard the receptacles when they have become substantially filled with dust, orv

the same in a manner that will enable the same to be folded into a substantially at condition for convenience in packaging and yet be readily distendable prior to insertion into the carpet sweeper. In one operative example, the dust receptacle 29 is formed from a suitably folded blank to provide the bottom wall 26, the side walls 30 and 3| which converge upwardly from said bottom wall, anda top flap 32 consisting of a continuation of the side wall 3i. The dust receptacle 29 also includes identical end walls 33 formed from suitable blanks to providev a bottom flange 34, which is adhesively or otherwise secured to the bottom wall 29, and side flanges 35 and 36, respectively adapted to be adhesively or otherwise secured to the walls 30 and 3| of the receptacle 29. The wall 35 is provided with slits (Fig. 6) disposed inwardly of the end walls 33 in order to provide a lip portion 31 adapted to be adjustably bent out of the plane of the wall 30 and toward the sweeper brush 29.

The bottom wall 28 is provided for its full length with a fold line 36 (Fig. 6) intermediate its edges, and each end wall 33 is provided with fold lines 39 disposed perpendicular to the fold line 33. Each of the flanges 34 is also provided with a-fold line 4D parallel with and disposed directly above the fold line 3B. Diagonal fold lines 4| are also formed in the end walls 33, thereby enabling said end walls to be folded and collapsed and folded in a manner similar to a Satchel fold. Thus, it will be apparent from Figs. 6 and 7 that upon upward folding of the bottom wall 28 and the flange 34, along the fold lines 38 and 46, respectively, and upon simultaneous inward folding of the end walls 33 along the vertical fold lines 39, a portion of the end walls 33 folds down against the bottom wall 2S, and other portions of the end walls 33 fold along the diagonal fold lines 4| and form tucks 42, which are disposed upon either side of the fold line 38 of the bottom wall 28, as will be apparent from Figs. 7 and 8. The top lap 32 is also pro vided with a fold line 43, thereby enabling a portion of said top flap to be folded down against the front wall 30.

A pair of thin, ferrous sheet metal discs 44 is mounted upon the top flap 32 of each of the dust receptacles 29. A U-shaped clip 45 (Fig. 5) is soldered at the base of the U to the center of each of the metal discs 44, and the legs 46 of said clip are extended through an opening 41 in the top flap located adjacent the fold line 43 and inwardly of the ends of the top flap 32. The legs 46 are spread apart and bent back against the inner side of the top nap 32 to assemble the discs 44 with said top nap.

The top wall portion of the housing I9 is provided with four holes 48 for the reception of brass screws 49, which are non-magnetic. Each of the brass screws 49 extends through `a disc 50 of insulating material and is threaded into a hole in a circular permanent magnet 5|. A pair of the permanent magnets 5| is arranged along each side of the housing I9 and the spacing of the permanent magnets of each pair corresponds withthe longitudinal spacing of the meta-l discs 44 carried by the naps 32 of the dust receptacles 29.` It will be understoodthat in certain in stances a single magnet 5| will be installed at each side of the housing to cooperate with only a single disc 44 on the top ap 32 of the dust receptacle 29. In the carpet sweeper disclosed herein, the transverse spacing of the permanent magnets 5| is such that the discs 44 are substantially concentric therewith when the dust receptacles 29 are mounted within the housing l In mounting the respective open dust receptacles 29 within the housing I0, the flap portion 32 is rst inserted through the open bottom of said housing so that it is disposed on the upper side of the brush 29, and then the portion of the receptacle having the side wall 3| is moved inwardly and in a direction toward the housing side wall |2 so that the bottom wall 28 of the receptacle clears the ange 21 of the brackets 26, and comes to `rest thereupon. The permanent magnets 5| will, of course, automatically attract the discs 44 so that the top flap 32 assumes the position shown in Fig. 3, thereby maintaining said top flap in its open or raised position. At the same time, the magnets 5| aid the brackets 26 in maintaining the dust receptacle 29 in place by holding the side wall 3| thereof adjacent the housing wall I2. It will be noted that the extremity of the top flap 32 lies close to the inner surface of rthe top wall portion of the housing I6 and that the lip portion 31 extends toward the brush 2U, so that any dust or other material picked up by the brush 2U as it is being rapidly rotated will be directed into the dust receptacle 29.

The removal of either of the receptacles 29 can be readily eiected by grasping the receptacle 29 and moving it toward the brush until the bottom Wall 28 :clears the iianges 21 of the brackets 26, and then bodily withdrawing the receptacle from within the housing I0. The permanent magnets 5| are of such strength that no diculty is presented in detaching the discs 44 therefrom by the withdrawing movement of the dust receptacles 29 from the housing The filled receptacles can be discarded and replaced by fresh, unused receptacles.

It will be understood that changes may be made in the arrangement and details of construction of both the carpet sweeper and the disposable dust receptacle disclosed herein, without departing from the spirit of the invention or the scope of the annexed claims.
